Terminating without callbacks
Describes ways to terminate optimization without a callback.
If you simply want to terminate optimization under circumstances defined by your application, then you do not necessarily need to write a callback to do so. Instead, you can invoke termination by these means:
In the C++ API, pass an instance of the class
IloCplex::Aborter
to an instance ofIloCplex
. Then call the methodIloCplex::Aborter::abort
to terminate optimization.In the Java API, pass an instance of the class
IloCplex.Aborter
to an instance ofIloCplex
. Then call the methodIloCplex.Aborter.abort
to terminate optimization.In the .NET API, pass an instance of the class
Cplex.Aborter
to an instance ofCplex
. Then call the methodCplex.Aborter.Abort
to terminate optimization.In the Callable Library (C API), call the routine
CPXsetterminate
to set a pointer to the termination signal. Initially, the value of the termination signal should be zero. When your application sets the termination signal to a nonzero value, then CPLEX will terminate optimization.In the Python API, use the
Aborter
class to terminate optimization. See mipex4.py for an example.
